You're clearly not understanding the concept. It's not about engaging an edge like carving. You need to put pressure to one side, even if its the slightest bit. You're probably not even aware you're doing this but if you're not then somehow you've figured out how to defy physics.. Or you're just sloppy

First up you might need to put pressure one one side to not catch an edge, I was like that for years so I know exactly what you are talking about but what you are not hearing is that I have learned to be able to ride completely flat based and I dont think im any kind of super badass snowboard guru / physics defying athlete lol.
Im talking no edge, no edge pressure, its like carrying your momentum across a flat box, people can learn to do that so I dont see why you cant accept that a person could learn to do the same on snow.
